Description

держит на оси 4 полуцилиндрическое гнездо 13, открывающеес  вбок, в которое закладываетс  штифт 14, общий дл  двух лезвий. Функци  его состоит в том, чтобы гарантировать симметрию движени  лезвий 2 и руко ток 3.it holds on axis 4 a semi-cylindrical socket 13, which opens laterally, into which pin 14, common to two blades, is laid. Its function is to ensure the symmetry of the movement of the blades 2 and the handle 3.

Работа цроисходит следующим образом.The work is as follows.

Когда ножницы приведены в действие, -каждый .из щатунов наклон етс  относительно продольной оси хот  бы одной из деталей, с которыми он св зан, чтобы скомпенсировать разницу положений двух последних, но сохран ет свой наклон посто нным по отношению к продольной оси ножниц, что способствует многократному увеличению движущегос  усили , а также равномерности передачи усили  на лезви . Усилие резани  очень быстро возрастает и всегда больщ-е, чем сила сопротивлени  резанию. Происходит рез.When the scissors are activated, each of the cranks tilts relative to the longitudinal axis of at least one of the parts with which it is associated, in order to compensate for the difference in the positions of the last two, but retains its tilt constant with respect to the longitudinal axis of the scissors, which contributes to the multiple increase in the driving force, as well as the uniform transfer of force on the blade. The cutting force increases very quickly and is always greater than the resistance to cutting. There is a cut.
